Q2. How does a teenager keep bad habits from controlling his or her life
They could lead to more serious habits.
To change bad habits is never easy, even with many attempts. There is a famous saying based on the philosophy of Aristotle: “We are what we repeatedly do.” In many ways, our lifestyle is the sum of choices we have made. We make a choice to do something, and then we repeat it over and over again. Soon that choice becomes automatic and forms a habit that is much harder to change. The good news is that we can change, if we understand how habits work.

According to modern psychology, we must first learn about the"habit cycle", which works like this:
Firstly, there is "cue", an action, event, or situation that acts as a signal to do something.
Secondly, there is a "routine", the regular action you take in response to the cue.
Thirdly, there is a "reward", the good thing or feeling we get from the routine.
For example, when we feel unhappy (cue), we eat lots of unhealthy snacks (routine), which makes us feel happy (reward) The reward makes us much more likely to continue the cycle, and the bad habit of relying on unhealthy snacks is formed.
